How I can generate .wasm file or .wast file for the following code:

import java.util.ArrayList;
public class NewClass2
{
    public static void main(String[] args)
    {
        ArrayList<String> lis = new ArrayList<>();
        lis.add("My");
        lis.add("Name");
        System.out.println(lis.get(2));
    }
}

Can anyone help me in this regard? I have check TeaVM, CheerpJ, etc, but unable to find to get generate web assembly code.

While one could, in theory, write a compiler from JavaScript to WebAssembly, converting JavaScript to WebAssembly is not currently possible or something that WebAssembly was explicitly designed for. If you want to write code that looks somewhat like JavaScript, but targets WebAssembly, the closest thing today is probably AssemblyScript: https://www.assemblyscript.org/.
